This dialog box presents a list of the interfaces available on the device,
allowing you to choose the interface which you want to view the
associated data for.
Whenever it can, 3Com Network Director will pre-select the interface in
the list associated with your selection on the 3Com Network Director
map. If you wish to change the selected interface, or customize the data
shown in the RMONView window, you can do so using the above dialog
box.
Update Rate
Determines how frequently the selected device will be polled for RMON
statistics data. The rate can be specified in multiples of 10 seconds. For
example, specifying an update rate of 6 indicates an update rate of every
60 seconds (i.e. 1 minute).
Community String
The Community field is initialized to the read/write community string
specified for the device in the 3Com Network Director Properties dialog
box. See “
Viewing Device Details” on page 229.
Clicking Edit launches the Edit Community dialog box, which allows you
to specify an alternative community string to be used to retrieve RMON
data from the selected device.

The selected View determines the data that will be displayed when the
RMONView window is launched. Clicking on Edit/Create View allows you
